SHANGHAI -- The founder of debt-laden tech conglomerate LeEco, Jia Yueting, has defied orders from Chinese regulators to return to the country before the end of 2017, saying he needed to stay in the United States as a fundraising for his electric car startup was making progress.

The Beijing branch of the China Securities Regulatory Commission issued a notice last week ordering Jia to return to China to sort out a mounting debt pile linked to his companies and protect investors' rights.

The executive said in a statement that he had asked his brother, Jia Yuemin, to meet the regulator face-to-face last Friday to provide a report after the notice was issued.

"I am deeply sorry and blame myself for the negative impact of LeEco's debt crisis," he said in the statement that was posted on his official WeChat account on Tuesday.

"The fundraising for Faraday Future in the United States is making significant progress and there are many tasks I need to push forward in order to ensure the production and timely delivery of the FF91," he said, referring to a luxury EV that LeEco is developing with Faraday Future.

Questions have been raised about the outlook for the FF91, given LeEco's spiraling cash problems as well as its decision to pull out of a joint project with U.K. sports automaker Aston Martin to develop RapidE electric car.

LeEco, an entertainment, electronics and electric vehicles group, has struggled to pay its debts after rapid expansion into multiple sectors sparked a cash crunch, a plunge in the shares of a listed unit and led to multiple defaults. At its peak LeEco owed creditors 10 billion yuan ($1.54 billion).

Struggling to support goals that included beating Elon Musk's Tesla in premium EV making, Jia has been trying to ride out the cash crunch by taking measures such cutting staff numbers and selling assets.

Jia said he had asked his wife, Gan Wei, and brother to represent him at Leshi Internet Information & Technology in exercising shareholder rights and handling the sale of assets. Jia stepped down as CEO of the group's main listed unit in May last year.

He also cited a single late payment in July as being one of the key causes of LeEco's cash-flow problems, saying it led to the freezing of his assets and prompted a slew of early loan recoveries. He said "false and malicious" reports had impacted the business.

Jia was placed on an official blacklist of debt defaulters in early December, a move taken by Chinese courts to put pressure on people and entities to repay debts.
